Legrand TX3 thermal magnetic circuit-breaker with 10kA breaking capacity, 4-pole configuration, 25A rating, B curve characteristic, and IP20 protection for reliable electrical installation safety and control.
The Legrand TX3 MCB 10000A 4 pole 25A curve B is a thermal magnetic circuit-breaker designed to provide reliable protection for wiring installations against overloads and short-circuits. With a breaking capacity of 10kA at 400V, this 4-pole device offers comprehensive protection and control capabilities for electrical installations. The B curve characteristic ensures a tripping threshold between 75A and 125A (3-5 times the rated current), making it suitable for standard residential and small commercial applications.
This circuit-breaker features advanced safety characteristics including IP20 protection against solid bodies larger than 12.5mm, energy limitation class 3 according to IEC 60898-1 standard, and can be supplied via copper cable, prong busbar, or fork busbar connections. The device is equipped with a special DIN rail clamp on the bottom side, allowing independent removal even when the fork busbar supplying the row remains in place. It includes a convenient label holder for circuit identification and clear ON/OFF indication printed on the handle with red and green backgrounds.
The TX3 MCB complies with substance-restriction requirements and has been designed with environmental consciousness. It can be equipped with Legrand DX3 auxiliaries and accessories, and can be connected to aluminium cable using Legrand DX3 terminal accessories. With rated voltage of 400V, rated insulation voltage of 500V, and impulse withstand voltage of 4kV, this circuit-breaker ensures maximum protection and reliability for electrical installations.
